Tool(s): A
web application (Figure
1) developed by Lorne Leonard
using Silverlight was developed for the sole purpose to answer this mini
challenge. The web application is designed to provide the visual and call web
services for performing the analytics. Figure 1
shows a scatter plot with date shown across the x-axis with time shown across
the y-axis. Overlaid on the scatter plot is a line graph showing the page size.
Search terms, persons and various other filters control the points
plotted. By clicking or hovering over a point,
the details of the wiki edit come into view. This allows us to determine who is
changing the web page and make these associations. By viewing more detail by a
particular person, we can review their edit patterns.

Detailed Answer:
Our first approach to answering the
factions represented in the wiki edits is to plot the edits against time and
the size of the web page to look for any patterns. Below in Figure 2, is a screen shot of these
results. The yellow rectangles mark the wiki edit event and the dark orange
line represents the wiki page size. First, we noticed that there is a regular
pattern of edits. About every two weeks, there is a mass amount of edits marked
in orange with Figure 3 and an
effort of "vandalism" to either blank or severely reduce the page
size.
Figure 2: Plotting wiki edit events
and wiki page size.
One of the application tools allows
the user to create a query that finds all wiki edits below a threshold value.
For example, Figure 4 shows the query
of finding all values below 1 byte and the list box on the right side shows the
results. The user is also able to click on the plotted rectangle to show its
properties such as the editor and the user can skip to the next event. We used
the same tool to find keywords such as "health-care" to plot the
locations and produce a list of editors.
Figure 3: About every 2 weeks, there
is a mass number of edits (highlighted in orange) followed by vandalism
reducing the page size to zero.

Short
Answer:
The above
evidence indicates that Alphanzo edited the web page to report confrontation
between Paraiso members and the Department of Health and the user
"moved" "Paraiso to
GUNNED DOWN SIX DOCTORS AND NURSES IN COLD BLOOD". We must point out that
this wiki edit does not conform to the standard wiki edit line. As it is
missing the byte size of the wiki page and replaced with an "m"
highlighted in yellow above. BakBOT, a user (perhaps automated) who regularly
reverts "vandalism" page edits, shortly removed Alphanzo edits.
However, comparing this BakBOT edit with other BakBOT edits a reference number
is missing. For example, the BakBOT edit below shows the reference number
highlighted in yellow. We speculate that this is a fake BakBOT edit.

Figure 5 shows the search results for
"gun" and by highlighting the rectangle event node we can see the
event values.
